Firefox Community Forum

I have many website icons from closed tabs at the top of the page that are crowding out my open tabs. I don't know why they keep appearing and I can't get rid of them. I've tried everything I can think of. I'm on an iMac, Sequoia 15.6.1

In many cases when one opens a new tab, the new one is opened on the right of the "parent tab". After reading the web page of the new tab, one often decides that the new tab is no longer useful and deletes it. Firefox automatically opens the tab on the right of the deleted tab, rather than resuming the "parent tab" on the left. This seems to be an ineffective design as probabilistically there are perhaps >90% chance one wants to go back to the "parent tab".

Q1: should Firefox change the default for resuming the left? Q2: is there a setting that user can change?

how can i force the active tab to show? i am fairly sure this feature was in a previous edition. I have a large number of tabs and sometimes an app or video will start and i am forced to go back and forth thru all the tabs just so i can stop them.

I have recently switched computers, and since it has been a while, I can't remember the setting on the 'about:config' page that I need to change to where when I open a new browser tab, it opens at the end of my list of tabs, rather than as the next tab. Thanks!
